Research Interests

The domain of specialization is Biotechnology and the fields of Synthetic Biology, Bioprocessing and Nanobiotechnology.

Current research projects focus on:

1- Synthetic Biology
Development of novel affinity reagents based on de novo designed synthetic and peptidomimetic scaffolds, selective for biopharmaceuticals (e.g. antibodies, recombinant proteins and protein isoforms). Molecular modeling, combinatorial libraries and high-throughput screening methods are utilized as tools for the design and selection of these novel affinity reagents.

2- Affinity bioseparation
Downstream processing using affinity reagents coupled to several separation matrices; design of process integration.

3- Smart-responsive platforms
Development of magnetic nanoparticles as smart responsive platforms for biomedical applications (e.g. drug delivery and theranostics); development of biosensing devices based on liquid crystals.
